The present invention relates to a high-power semiconductor laser having low divergence and low astigmatism, this laser being including, in an active layer, a first part in the form of a narrow monomode stripe with transverse index guiding terminating in a second part flaring out from the first part, also with transverse index guiding. The method dispenses a single material using a pneumatic dispensing system having a single output including first and second shotmeters having first and second meters, first and second encoders and first and second pressure transducers. An offset fly lens array converts light energy from the illumination field into an offset pattern of illumination spots. The lamp shade has an open end connected to an outer periphery of the lamp holder; and the LED module, the thermal module, and the heat transfer member are received in a space defined in the lamp shade. The selected template, the updated template, or the new template is then used to extract receipt data from the receipt image.
